: I'm not Kevin but I think the answer is this: Affleck was just an actor who auditioned (not a friend yet) and got the part. He had been in "Dazed and Confused" and I think "School Ties" already - giving him the bad guy roles. Anyway, they used to all hang out after shooting, playing EA hockey and I believe they just meshed. If you listen to the banter in the commentaries that Ben is involved on you can tell that those two have very similar senses of humor. ANyway, that's how it's been told in the past.
